This specification details the performance requirements of a
preformed sealer (compound), which is applied to the Body Floor
Pan. This material adheres to the Electrodeposition Primer (ELPO)
paint layer on the Body to prevent water, dust or air
intrusion.

Material Description. The material must be a
smooth and homogenous mixture; free of air, lumps and foreign
particles. Material must show no sign of trapped air from either an
external observation or a sectional view before and after curing
and must not be tacky. The material must not accelerate the rusting
of the substrate over which it is applied.

Symbols. Not applicable.

Applicability. All vehicles. These sealers are
manually installed in the Paint Shop, on the Sealer Line.

Remarks.

Technology Approval Documentation. At the conclusion of testing
to this specification, the Supplier must provide a document package
with the following:

Product Data. Documentation of all attributes and test results
are required for the material, per Section 3 of this specification.
All test panels should be identified and photographed for full
documentation.

Bake Charts. A Bake window that identifies the
Bake Conditions where the sealer meets and no longer meets all
requirements of the specification, must be provided. Key Product
Characteristics to include, at minimum; Initial Adhesion and
Adhesion after Cycle Test. The Bake Chart is to reflect; Time at
Metal Temperature on x-axis (minimum range: 0 minutes to 90
minutes) and Temperature on y-axis (minimum range: 130 °C to 200
°C). Additional direction to be provided by the approving material
engineer.

Additional information may be requested by the responsible GM
Engineer, including Manufacturing site and trend charting of these
attributes for (×) number of the initial production material
batches.
